[0058] In actual operation, the motor 304 uses a reciprocating rotation method to drive the rotating ring 302 to rotate back and forth, so as to avoid the connection lines and pipes from getting tangled.

[0059] The outer periphery of the rotating ring 302 is provided with several fixing blocks 502, which are welded and fixed to the rotating ring 302 for connecting the guide rod 501.

[0060] The other end of the support column 2 is equipped with a rotating shaft 306.

[0064] The drilling and anchoring mechanism 5 also includes several parallel guide rods 501, which are fixedly connected to the fixing block 502 and the connecting rod 307 of the rotating frame 3.

[0065] The guide rod 501 has a movable groove 503 inside, and a movable block 505 is slidably connected to the movable groove 503. The movable block 505 is made of high-strength alloy material and is used to connect the slide block 404.

[0066] Guide grooves 504 are provided on both sides of the inner wall of the movable groove 503, and guide blocks 506 are provided on both sides of the movable block 505. The guide blocks 506 are adapted to the guide grooves 504 and slide along the guide grooves 504 to ensure the smoothness and straightness of the movement of the movable block 505 and improve the working accuracy.

[0067] The guide rod 501 is provided with a positioning plate 507 at the end away from the movable block 505. The positioning plate 507 is made of thick steel plate. The drill rod of the rock drill 511, the grouting pipe 512 and the anchor rod connected to the anchoring machine 513 all slide through the positioning plate 507.

[0068] The positioning plate 507 is equipped with guide sleeves made of wear-resistant material, which are compatible with the drill rod, grouting pipe 512, and anchor bolt connected to it. The center distance of several guide sleeves from the guide rod 501 is the same, ensuring that rock drilling, grouting, and anchoring operations are carried out in the same position. The positioning plate 507 is used to guide the movement direction of the drill rod, grouting pipe 512, and anchor bolt, further improving the operation accuracy.

[0069] The rock drill 511, grouting pipe 512, and anchor bolt 513 are all fixedly connected to the movable block 505 by bolts. Specifically, the rock drill 511 is connected to the movable block 505, the drill rod of the rock drill 511 passes through the guide sleeve of the corresponding positioning plate 507, the end of the grouting pipe 512 near the inlet is connected to the movable block 505, and the end near the outlet passes through the guide sleeve of the corresponding positioning plate 507, the jaws of the anchor bolt 513 are connected to the movable block 505, and the end of the anchor bolt connected to it passes through the guide sleeve of the corresponding positioning plate 507. Then, the movable block 505 of the rock drill 511, grouting pipe 512, or anchor bolt 513 rotates to the slide 404 and connects with the slide 404. Under the drive of the slide 404, it can move along the movable groove 503 of the guide rod 501 to realize the corresponding operation feed.

[0070] Both the slide 404 and the movable block 505 are equipped with magnets 405. The magnets 405 are made of strong magnetic material. The magnets 405 in the slide 404 are used to attract the magnets 405 in the movable block 505, so as to realize the quick connection and separation of the slide 404 and the movable block 505, which facilitates switching between different working mechanisms.

[0071] When in use, the equipment is moved to the construction site by the trolley 101, and the robotic arm 102 is operated to adjust the support column 2 and the drilling and anchoring mechanism 5 to the appropriate construction position and angle.

[0072] Then, the motor 304 of the rotating frame 3 is controlled to rotate the rotating ring 302, rotating the guide rod 501 of the rock drill 511 to the position corresponding to the slide 4. The slide 404 and the movable block 505 of the rock drill 511 are connected by the magnet 405. The hydraulic cylinder 402 is started, driving the slide 404 to move the movable block 505 and the rock drill 511 along the movable groove 503 of the guide rod 501. Under the guidance of the positioning plate 507 and the guide sleeve, the drill rod of the rock drill 511 performs drilling operations on the rock mass.

[0073] After drilling is completed, the hydraulic cylinder 402 drives the rock drill 511 to reset, and the control motor 304 drives the rotating ring 302 to rotate. The slide 404 separates from the movable block 505 corresponding to the rock drill 511. The guide rod 501 corresponding to the grouting pipe 512 is rotated to the position corresponding to the slide frame 4, and the slide 404 is connected to the movable block 505 corresponding to the grouting pipe 512 through the magnet 405.

[0074] Start the hydraulic cylinder 402 to push the grouting pipe 512 to move along the guide rod 501, pass through the guide sleeve of the positioning plate 507 and enter the borehole to carry out the grouting operation.

[0075] After grouting is completed, the grouting pipe 512 is reset, and the rotating ring 302 is rotated again. The sliding block 404 is separated from the movable block 505 corresponding to the grouting pipe 512. The guide rod 501 corresponding to the anchor insertion machine 513 is rotated to the working position, and the sliding block 404 is connected to the movable block 505 corresponding to the anchor insertion machine 513.

[0076] Start the hydraulic cylinder 402 to drive the anchor insertion machine 513 to insert the anchor rod into the borehole through the guide sleeve of the positioning plate 507, thus completing the anchor insertion operation.

[0077] After completing the above three procedures at the same construction location, the position of the support column 2 is adjusted by the robotic arm 102 to proceed to the next location, and the above steps are repeated.

[0078] After all operations are completed, all components are reset, and the operating trolley 101 moves the equipment to the storage location.
